Influence of soil temperature, rainfall, and planting and harvest dates on Chaetocnema confinis (Coleoptera: Chrysomelidae) damage to sweetpotato roots.

A study was carried out in 10 counties of North Carolina from 2004 to 2006 to determine the effect of planting and harvest times on flea beetle, Chaetocnema confinis Crotch (Coleoptera: Chrysomelidae), damage to sweetpotato, Ipomoea batatas (L.), storage roots. Planting and harvesting of sweetpotatoes later in the season resulted in less damage than early planting and harvesting.
